Staying warm without overheating is critical. The Nano-Air® Light Hybrid Vest traps heat at your core—where you need it most—but lets off steam to keep you dry and comfortable. The front of the vest warms and protects with warm-when-wet FullRange™ insulation (40-g) sandwiched between a plain-weave liner and a lightweight yet durable, weather-shedding 100% nylon ripstop shell with a DWR (durable water repellent) finish. The back of the vest features a super stretchy, airy waffle knit that swiftly wicks moisture, controls odor and dissipates heat. The center-front zipper has a zipper garage for comfort on the chin, and zippered handwarmer pockets rest easily under a harness or pack. Stretch binding at the armholes and hem seal in warmth.

Water Resistant

DWR (durable water repellent) fabric finish repels light rain and snow and decreases dry times. When DWR is used in conjunction with a waterproof/breathable barrier, the DWR finish keeps the outer fabric from becoming saturated so that the breathable barrier can do its job.

Odor Resistant

Polygiene® odor control permanently protects your garments from smelling like a middle school locker room. Sweat itself is odorless, but it creates the conditions that bacteria need to multiply, and some of those bacteria produce odors. Polygiene permanent odor control stops the growth of odor-causing bacteria on fabrics, so you can wear more and wash less.

Active only on the fabric surface, Polygiene permanent odor control does not interfere with perspiration or with the skin’s natural bacterial flora. Polygiene particles are more than 100 times larger than nanoparticles and therefore are too large to penetrate to the skin’s barrier. Polygiene-treated fabrics have received Medical Class 1 approval in Europe, the same class that includes bandages.
